wegfallen vs verschwinden
to disappear
'verschwinden' and 'wegfallen' can both mean that something is no longer there or no longer plays a role. 'verschwinden' is broader and can also be used for visible things, people, or feelings. Something is then no longer visible, no longer findable, or dissolves. 'wegfallen' is used more for appointments, rules, costs, reasons, or other abstract things. It often sounds as if something is being removed or is no longer needed. If the bus is no longer visible, it 'verschwindet'; if an appointment is canceled, it 'fällt weg'.
